A big part of Valves steamy vision of the future will be the ability to play full-fledged PC games on a relatively small living room machine, by streaming them to the Steam client from a main gaming PC in another room. (Much like Remote Play on the PS4 and Vita, or NVIDIAs GameStreaming from a PC to its Shield handheld.) Although the SteamOS and Steam Machine projects are still a long way off, Valve says itll start beta testing of this particular feature by the end of this year.
